The amount that Jane and Luis each had in the end is the same. Make the amount that each had in the end the same. LCM of 2 and 1 is 2.
Total amount that Jane and Luis had at first
= 5 u + 10 u
= 15 u
15 u = 120
1 u = 120 ÷ 15 = 8
Total amount that Jane and Luis spent
= 3 u + 8 u
= 11 u
= 11 x 8
= $88
Answer(s): $88
